Title: Temperature detector
Inventor: MURAHASHI TOSHIAKI
IPC: G01J5/38
Filed: 1978-07-10
Abstract: PURPOSE:To secure the measurement of the temperature at the area where the direct viewing is impossible in a high sensitivity and high accuracy by leading the radiant light of the temperature-sensing element via the optical waveguide and then carrying out the photo-acoustic conversion by making use of the selective absorbing property of the gas. CONSTITUTION:The radiant light given from temperature-sensing element 1 is led to the temperature detection part via optical fiber 10 and the like which functions as an optical waveguide. The radiant light is then changed into the intermittent light by light chopper 11 provided at the front step of the detection part. This intermittent light then enters gas cell 13 filled with the gas featuring the absorption wavelength within the optical spectrum of the radiant light through window 12. The radiant light in cell 13 receives the absorption corresponding to the excitation to the vibration level which is proper to the gas within the cell. This change is caught by piezoelectric transducer 15 provided in the cell and then converted into the electric signal to be led to signal process electronics 16. As a result, the temperature can be measured in a high sensitivity and high accuracy at the area where the direct viewing is impossible.

In these equations, sgn is 1 during following a preceding car and -1 during merging.  A constant acceleration/deceleration control rule where a car speed reaches a target car speed at a target position or a target inter- vehicle distance can be applied, and the control rule can be applied to the entire speed control of automatic operation to uniformly express speed control rules during acceleration/deceleration.

Title: Varying magnetic field measuring apparatus
Inventor: SUZUKI YOSHINORI
IPC: A61B5/055
Filed: 1990-03-30
Abstract: PURPOSE:To enable the measuring of a magnetic field about a magnetic field component only in a direction of a main magnetic field while eliminating a drift in the results of a measurement by receiving a magnetic resonance signal from a sample to calculate a varying magnetic field applied to a sample from a phase difference of a detection output of the signal at each specified time. CONSTITUTION:A magnetic resonance signal amplified with a transmitting/receiving circuit 3 is inputted into a detection circuit 4, an output waveform of which 4 is inputted into an A/D converter 5 and a conversion output is inputted into a phase detection circuit 6 to calculate a phase. An output of the circuit 6 is inputted into a phase difference computing circuit 7 to determine a phase differential value. Then, a varying magnetic field is calculated from the phase difference value calculated with the phase difference computing circuit 8. In this manner, the magnetic resonance signal from the sample is processed to measure the varying magnetic field applied to the sample and hence, the results of measurement can be obtained as for a magnetic field component only in a direction of a main magnetic field of the varying magnetic field applied to the sample. This also eliminates the need for an integrator for the detection of the magnetic resonance signal and moreover, a reference wave for the detection of a phase normally used in the detection of the magnetic resonance signal is so stable as to cause no drift in the varying magnetic field measured.

Each character is recognized by matching it with a model stored in a reference pattern storing part 23. The model is described by feature values, i.e. the positions of the maximum and minimum values and formed in consideration of feature values extracted from the high quality of a character to be practically inspected and an ideal state. Consequently, binary image processing is stabilized and the processing time of the succeeding deciding processing can be shortened.
